I used POR-15 on my battery tray about 4 years ago, and today it pretty much looks like the day I put it on.
I used Rust Bullet the exposed parts of my front spindles/uprights when I did the front end rebuild. It's gotten quite dirty since then, but there is no sign of any rust or corrosion.
Because POR-15 is UV light sensitive, I tend to use it on hidden items in dark areas (under hood for example). It's glossy black and needs to be top coated if exposed to sun. It also has a somewhat involved surface prep requirement, but the starter kit contains all that's needed.
Rust Bullet is silver, and has no UV light issues and no surface prep needed other than wire brushing.
I'm not able to pick a favorite.
